Creswell Crags Robin Hood Cave Ochre Horse Rib Bone Carving Decipherment Update 1.0

This posting is Update 1.0 to my previously posted decipherment of the Creswell Crags "Ochre Horse" rib bone carving, showing that the calendric astronomy of stars is continued on the rib bone if it is turned 180 degrees, thus covering all the heavens and all the seasons and marking divisions of the heavens that would suggest a lunar and solar mesh. This update also puts the date closer to 10500 B.C. and shows that the deeply incised lines on the rib bone were added to separate the stars noted on one half of the rib bone.

A more detailed posting will follow as Update 2.0.

That engraved bone, now popularly called the "Robin Hood Cave Horse" after the cave in which it was discovered in 1876, is dated by the archaeologists to the Ice Age ca. 12500 years ago. It is the oldest artifact (British artefact) of this kind ever found in northern Europe and, as a stroke of luck for those interested, is currently on display at the British Museum until May 26, 2013 in the British Museum exhibition: Ice Age Art: Arrival of the Modern Mind.
See the reviews at:

• “Not even Leonardo surpassed this” -- The Guardian
• “I can’t remember the last time I saw a show with so many rare and beautiful objects” -- The Telegraph
• “The exhibition everyone should see” -- The Times
• “Astonishing” -- Metro

For today, only this updated decipherment, no text.
In the course of time I will reveal how I arrived at this solution. Enjoy.

"Creswell Crags. The Ochre Horse. This original fragment of a rib bone contains the oldest known carving of its type in Britain. The horse was carved approximately 12,500 years ago and was on temporary display at the small museum at Creswell Crags to November 2009 (although a replica of the ochre horse is always on display). It was found on the 29th June in 1876 at the back of the western chamber in the 'Robin Hood Cave' in Creswell Crags. Sieveking 855, British Museum.

The astronomical interpretations that surround the photograph are by Andis Kaulins, April 2, 2013, and are not part of the original photograph of the Ochre Horse. The forms of stellar constellations are taken from Starry Night Pro as is also the sky map of the stars turned 180 degrees to emphasize the stars that the ochre horse rib bone portrays when it is turned, i.e. those stars on or between the Winter Solstice and Spring Equinox in ca. 10500 B.C.
